BACKGROUND OF THE INVENTION

Poly(ADP-ribose)polymerase (PARP) or poly(ADP-ribose) synthase (PARS) has an essential role in facilitating DNA repair, controlling RNA transcription, mediating cell death, and regulating immune response. These actions make PARP inhibitors targets for a broad spectrum of disorders. PARP inhibitors have demonstrated efficacy in numerous models of disease, particularly in models of ischemia reperfusion injury, inflammatory disease, degenerative diseases, protection from adverse effects of cytotoxic compounds, and the potentiation of cytotoxic cancer therapy. PARP has also been indicated in retroviral infection and thus inhibitors may have use in antiretroviral therapy. PARP inhibitors have been efficacious in preventing ischemia reperfusion injury in models of myocardial infarction, stroke, other neural trauma, organ transplantation, as well as reperfusion of the eye, kidney, gut and skeletal muscle. Inhibitors have been efficacious in inflammatory diseases such as arthritis, gout, inflammatory bowel disease, CNS inflammation such as MS and allergic encephalitis, sepsis, septic shock, hemorrhagic shock, pulmonary fibrosis, and uveitis. PARP inhibitors have also shown benefit in several models of degenerative disease including diabetes (as well as complications) and Parkinson's disease. PARP inhibitors can ameliorate the liver toxicity following acetaminophen overdose, cardiac and kidney toxicities from doxorubicin and platinum based antineoplastic agents, as well as skin damage secondary to sulfur mustards. In various cancer models, PARP inhibitors have been shown to potentiate radiation and chemotherapy by increasing cell death of cancer cells, limiting tumor growth, decreasing metastasis, and prolonging the survival of tumor-bearing animals.

PARP1 and PARP2 are the most extensively studied PARPs for their role in DNA damage repair. PARP1 is activated by DNA damage breaks and functions to catalyze the addition of poly (ADP-ribose) (PAR) chains to target proteins. This post-translational modification, known as PARylation, mediates the recruitment of additional DNA repair factors to DNA lesions.

Following completion of this recruitment role, PARP auto-PARylation triggers the release of bound PARP from DNA to allow access to other DNA repair proteins to complete repair. Thus, the binding of PARP to damaged sites, its catalytic activity, and its eventual release from DNA are all important steps for a cancer cell to respond to DNA damage caused by chemotherapeutic agents and radiation therapy.

Inhibition of PARP family enzymes has been exploited as a strategy to selectively kill cancer cells by inactivating complementary DNA repair pathways. A number of pre-clinical and clinical studies have demonstrated that tumor cells bearing deleterious alterations of BRCA1 or BRCA2, key tumor suppressor proteins involved in double-strand DNA break (DSB) repair by homologous recombination (HR), are selectively sensitive to small molecule inhibitors of the PARP family of DNA repair enzymes. Such tumors have deficient homologous recombination repair (HRR) pathways and are dependent on PARP enzymes function for survival. Although PARP inhibitor therapy has predominantly targeted SRCA-mutated cancers, PARP inhibitors have been tested clinically in non-SRCA-mutant tumors, those which exhibit homologous recombination deficiency (HRD).

It is believed that PARP inhibitors having improved selectivity for PARP1 may possess improved efficacy and reduced toxicity compared to other clinical PARP1/2 inhibitors. It is believed also that selective strong inhibition of PARP1 would lead to trapping of PARP1 on DNA, resulting in DNA double strand breaks (DSBs) through collapse of replication forks in S-phase. It is believed also that PARP1-DNA trapping is an effective mechanism for selectively killing tumor cells having HRD. An unmet medical need therefore exists for effective and safe PARP inhibitors. Especially PARP inhibitors having selectivity for PARP1.

The term “optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. For example, “optionally substituted alkyl” means either “alkyl” or “substituted alkyl” as defined above. Further, an optionally substituted group may be un-substituted (e.g., —CH₂CH₃), fully substituted (e.g., —CF₂CF₃), mono-substituted (e.g., —CH₂CH₂F) or substituted at a level anywhere in-between fully substituted and mono-substituted (e.g., —CH₂CHF₂, —CH₂CF₃, —CF₂CH₃, —CFHCHF₂, etc.). It will be understood by those skilled in the art with respect to any group containing one or more substituents that such groups are not intended to introduce any substitution or substitution patterns (e.g., substituted alkyl includes optionally substituted cycloalkyl groups, which in turn are defined as including optionally substituted alkyl groups, potentially ad infinitum) that are sterically impractical and/or synthetically non-feasible. Thus, any substituents described should generally be understood as having a maximum molecular weight of about 1,000 daltons, and more typically, up to about 500 daltons.

An “effective amount” or “therapeutically effective amount” refers to an amount of a compound administered to a mammalian subject, either as a single dose or as part of a series of doses, which is effective to produce a desired therapeutic effect.

“Treatment” of an individual (e.g. a mammal, such as a human) or a cell is any type of intervention used in an attempt to alter the natural course of the individual or cell. In some embodiments, treatment includes administration of a pharmaceutical composition, subsequent to the initiation of a pathologic event or contact with an etiologic agent and includes stabilization of the condition (e.g., condition does not worsen) or alleviation of the condition.

“Synergy” or “synergize” refers to an effect of a combination that is greater than additive of the effects of each component alone at the same doses.

Method of Treatment

Disclosed herein are methods of treatment of a disease in which inhibition of PARP is beneficial, the method comprising administering a compound disclosed herein. Also disclosed herein are methods of treatment of a disease in which inhibition of PARP1 is beneficial, the method comprising administering a compound disclosed herein. In some embodiments, the disease is cancer. In some embodiments, the cancer is breast cancer, ovarian cancer, pancreatic cancer, prostate cancer, a hematological cancer, a gastrointestinal cancer such as gastric cancer and colorectal cancer, or lung cancer. In some embodiments, the cancer is breast cancer, ovarian cancer, pancreatic cancer, or prostate cancer. In some embodiment, the cancer is leukemia, colon cancer, glioblastoma, lymphoma, melanoma, or cervical cancer.

In some embodiments, the cancer comprises a BRCA1 and/or a BRCA2 mutation.

In some embodiments, the cancer comprising a BRCA1 and/or a BRCA2 mutation is bladder cancer, brain & CNS cancers, breast cancer, cervical cancer, colorectal cancer, esophagus cancer, Hodgkin lymphoma, non-Hodgkin lymphoma, kidney cancer, leukemia, lung cancer, melanoma, myeloma, oral cavity cancer, ovarian cancer, pancreatic cancer, prostate cancer, skin cancer, stomach cancer, thyroid cancer, or uterus cancer.

In some embodiments, the cancer is a cancer deficient in Flomologous Recombination (FIR) dependent DNA DSB repair activity. The FIR dependent DNA DSB repair pathway repairs double-strand breaks (DSBs) in DNA via homologous mechanisms to reform a continuous DNA helix. The components of the FIR dependent DNA DSB repair pathway include, but are not limited to, ATM (NM_000051), RAD51 (NM 002875), RAD51 LI (NM_002877), RAD51 C (NM 002876), RAD51 L3 (NM 002878), DMC1 (NM 007068), XRCC2 (NM_005431), XRCC3 (NM_005432), RAD52 (NM 002879), RAD54 L (NM 003579), RAD54B (NM 012415), BRCA1 (NM_007295), BRCA2 (NM 000059), RAD50 (NM 005732), MRE11 A (NM_005590) and NBS1 (NM 002485). Other proteins involved in the FIR dependent DNA DSB repair pathway include regulatory factors such as EMSY. In some embodiments, the cancer which is deficient in FIR dependent DNA DSB repair comprises one or more cancer cells which have a reduced or abrogated ability to repair DNA DSBs through that pathway, relative to normal cells i.e. the activity of the FIR dependent DNA DSB repair pathway may be reduced or abolished in the one or more cancer cells.

In some embodiments, the activity of one or more components of the FIR dependent DNA DSB repair pathway is abolished in the one or more cancer cells of an individual having a cancer which is deficient in FIR dependent DNA DSB repair.

In some embodiments, the cancer cells have a BRCA1 and/or a BRCA2 deficient phenotype i.e. BRCA1 and/or BRCA2 activity is reduced or abolished in the cancer cells. Cancer cells with this phenotype may be deficient in BRCA1 and/or BRCA2, i.e. expression and/or activity of BRCA1 and/or BRCA2 may be reduced or abolished in the cancer cells, for example by means of mutation or polymorphism in the encoding nucleic acid, or by means of amplification, mutation or polymorphism in a gene encoding a regulatory factor, for example the EMSY gene which encodes a BRCA2 regulatory factor. BRCA1 and BRCA2 are known tumor suppressors whose wild-type alleles are frequently lost in tumors of heterozygous carriers. Amplification of the EMSY gene, which encodes a BRCA2 binding factor, is also known to be associated with breast and ovarian cancer. Carriers of mutations in BRCA1 and/or BRCA2 are also at elevated risk of certain cancers, including breast cancer, ovarian cancer, pancreatic cancer, prostate cancer, a hematological cancer, gastrointestinal cancer, and lung cancer.

To minimize the risks of off-target effects, it is desirable for drug molecules to possess selectivity for a specific target.

Avoiding inhibition of PARP family isoforms beyond PARP1 may be important in minimizing toxicities that may arise from inhibition of non-ARP isoforms. The pharmacology of inhibiting PARP isoforms beyond PARP1 may drive toxicities that reduce the therapeutic index for agents that possess lower selectivity's for PARP1 against PARP isoforms. PARP3, like PARP1, plays a role in DNA damage but has also been found to be a key player in the integrity of the mitotic spindle and in telomerase integrity (Boehler, C., Gauthier, L R., Mortusewicz O. et al. Poly(ADP-ribose) polymerase 3 (PARP3), a newcomer in cellular response to DNA damage and mitotic progression. PNAS, Jan. 26, 2011, 108 (7) 2783-2788) PARP5A also known as Tankyrase 1, plays key roles in Wnt signaling and telomere length (Kulak, O., Chen, H., Holohan B. et al. Disruption of Wnt/β-Catenin Signaling and Telomeric Shortening Are Inextricable Consequences of Tankyrase Inhibition in Human Cells. Mol Cell Biol. 2015 July; 35(14), 2425-2435). PARP6 is an essential microtubule-regulatory gene in mice, germline mutations in PARP6 that abrogate the catalytic activity has negative effects on neuronal function in humans (Vermehren-Schmaedick, A., Huang J. Y., Levinson, M. et al. Characterization of PARP6 Function in Knockout Mice and Patients with Developmental Delay. Cells, 2021 June; 10(6), 1289). PARP7 catalytic inhibition causes hyper stimulatory effects on type one interferon producing an autoimmune phenotype (Gozgit, J. M., Vasbinder, M. M., Abo. R. P. et al. PARP7 negatively regulates the type I interferon response in cancer cells and its inhibition triggers antitumor immunity. Volume 39, Issue 9, 13 Sep. 2021, Pages 1214-1226). While the exact function of PARP8 has not been established, its knockout has been shown to induce mitotic and nuclear morphology defects and a decrease in cellular viability (Vyas, S. Chesarone-Cataldo M., Todorova, T., et al. A Systematic Analysis of the PARP Protein Family Identifies New Functions Critical for Cell Physiology. Nat. Commun. 2013, 4 (1), 2240). PARP10 has been described as a MYC interacting protein with tumor suppressor activities (Yu, M., Schreek, S., Cerni, C. et al. PARP-10, a novel Myc-interacting protein with pols (ADP-ribose) polymerase activity, inhibits transformation. Oncogene, 2005 volume 24, pages 1982-1993).

Dosing

In certain embodiments, the compositions containing the compound(s) described herein are administered for prophylactic and/or therapeutic treatments. In certain therapeutic applications, the compositions are administered to a patient already suffering from a disease or condition, in an amount sufficient to cure or at least partially arrest at least one of the symptoms of the disease or condition. Amounts effective for this use depend on the severity and course of the disease or condition, previous therapy, the patient's health status, weight, and response to the drugs, and the judgment of the treating physician. Therapeutically effective amounts are optionally determined by methods including, but not limited to, a dose escalation and/or dose ranging clinical trial.

In prophylactic applications, compositions containing the compounds described herein are administered to a patient susceptible to or otherwise at risk of a particular disease, disorder or condition. Such an amount is defined to be a “prophylactically effective amount or dose.” In this use, the precise amounts also depend on the patient's state of health, weight, and the like. When used in patients, effective amounts for this use will depend on the severity and course of the disease, disorder or condition, previous therapy, the patient's health status and response to the drugs, and the judgment of the treating physician. In one aspect, prophylactic treatments include administering to a mammal, who previously experienced at least one symptom of or risk factor for the disease being treated and is currently in remission, a pharmaceutical composition comprising a compound described herein, or a pharmaceutically acceptable salt thereof, in order to prevent a return of the symptoms of the disease or condition.

In certain embodiments wherein the patient's condition does not improve, upon the doctor's discretion the administration of the compounds are administered chronically, that is, for an extended period of time, including throughout the duration of the patient's life in order to ameliorate or otherwise control or limit the symptoms of the patient's disease or condition.

In certain embodiments wherein a patient's status does improve, the dose of drug being administered is temporarily reduced or temporarily suspended for a certain length of time (i.e., a “drug holiday”). In specific embodiments, the length of the drug holiday is between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, or more than 28 days. The dose reduction during a drug holiday is, by way of example only, by 10%-100%, including by way of example only 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and 100%.

Once improvement of the patient's conditions has occurred, a maintenance dose is administered if necessary. Subsequently, in specific embodiments, the dosage or the frequency of administration, or both, is reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. In certain embodiments, however, the patient requires intermittent or daily treatment on a long-term basis upon any recurrence of symptoms.

The amount of a given agent that corresponds to such an amount varies depending upon factors such as the particular compound, disease condition and its severity, the identity (e.g., weight, sex) of the subject or host in need of treatment, but nevertheless is determined according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, the condition being treated, and the subject or host being treated.

In general, however, doses employed for adult human treatment are typically in the range of 0.01 mg-5000 mg per day. In one aspect, doses employed for adult human treatment are from about 1 mg to about 1000 mg per day. In one embodiment, the desired dose is conveniently presented in a single dose or in divided doses administered simultaneously or at appropriate intervals, for example as two, three, four or more sub-doses per day.

In one embodiment, the daily dosages appropriate for the compound described herein, or a pharmaceutically acceptable salt thereof, are from about 0.01 to about 50 mg/kg per body weight. In some embodiments, the daily dosage or the amount of active in the dosage form are lower or higher than the ranges indicated herein, based on a number of variables in regard to an individual treatment regime. In various embodiments, the daily and unit dosages are altered depending on a number of variables including, but not limited to, the activity of the compound used, the disease or condition to be treated, the mode of administration, the requirements of the individual subject, the severity of the disease or condition being treated, and the judgment of the practitioner.

Toxicity and therapeutic efficacy of such therapeutic regimens are determined by standard pharmaceutical procedures in cell cultures or experimental animals, including, but not limited to, the determination of the LD₁₀ and the ED₉₀. The dose ratio between the toxic and therapeutic effects is the therapeutic index and it is expressed as the ratio between LD₅₀ and ED₅₀. In certain embodiments, the data obtained from cell culture assays and animal studies are used in formulating the therapeutically effective daily dosage range and/or the therapeutically effective unit dosage amount for use in mammals, including humans. In some embodiments, the daily dosage amount of the compounds described herein lies within a range of circulating concentrations that include the ED₅₀ with minimal toxicity. In certain embodiments, the daily dosage range and/or the unit dosage amount varies within this range depending upon the dosage form employed and the route of administration utilized.

In any of the aforementioned aspects are further embodiments in which the effective amount of the compound described herein, or a pharmaceutically acceptable salt thereof, is: (a) systemically administered to the mammal; and/or (b) administered orally to the mammal; and/or (c) intravenously administered to the mammal; and/or (d) administered by injection to the mammal; and/or (e) administered topically to the mammal; and/or (f) administered non-systemically or locally to the mammal.

In any of the aforementioned aspects are further embodiments comprising single administrations of the effective amount of the compound, including further embodiments in which (i) the compound is administered once a day; or (ii) the compound is administered to the mammal multiple times over the span of one day.

The objective of this study is to evaluate the effect of invention compounds on cell proliferation through the cell viability assay in DLD-1 BRCA2(−/−) and parental isogenic pair and MDA-MB-436 (mutated BRCA1) cell lines. The CellTiter-Glo (CTG) based cell viability assay is designed to determine the number of viable cells in the culture because of compound effect, by quantifying ATP, which indicates the presence of metabolically active cells.

DLD-1 BRCA2(−/−) and parental isogenic pair were cultured in RPMI 1640 supplemented with 10% fetal bovine serum (FBS), and MDA-MB-436 cells were cultured in DMEM supplemented with 10% FBS. Both are culture at 37° C. with 5% CO₂. Invention compounds were distributed to the 384 well plate (Corning, 3764) using Echo acoustic liquid handler to form a 1:3 serially diluted final concentration with top dose of 10 or 30 μM. The cells were seeded into the plate in the density of 50 cells/well (DLD-1 parental), 200 cells/well (DLD-1 BRCA2−/−), or 500 cells/well (MDA-MB-436). After a short spun, the cells were cultured in a well moisturized incubator at 37° C. with 5% CO₂ for 7 days without disturbance. The cell viability was measured by CellTiter Glo 2.0 assay kit (Promega, G9243), and growth inhibition rate was calculated and plotted against final compound concentration, and the data were fitted in Xfit to generate IC₅₀.

Example B: Biochemical (FP) Assay

Assays based on fluorescent polarization (FP) have been widely utilized in drug discovery due to the homogenous format, robust performance and lack of interference seen in other assays. To characterize our compounds, we utilized an assay measuring the displacement of a commercially available fluorescently labeled PARP 1/2 inhibitor (PARPi-FL, Tocris Biosciences, #6461) as exemplified in assays performed in WO2014/064149 and WO2021/013735A¹. The assay was performed utilizing the following method:

Compounds were dissolved in DMSO an Echo550 liquid handler was utilized to make serial dilations in the desired concentration range in Optiplate-384F plates. 100% DMSO was used for the high (with protein) and low (without protein) control samples. 20 nL of compound or DMSO alone was added to individual assay plate wells.

PARP1 and PARP2 protein were expressed, purified and diluted in assay buffer containing 50 mM Tris pH 8.0, 0.001% Triton X-100, 10 mM MgCl₂, 150 mM NaCl to a final concentration of 20 nM. The PARPi-FL was then added at a final concentration of 3 nM.

The assay plate is centrifuged at 1000 rpm for 1 min and incubated for 4 h at room temperature.

The fluorescent polarization is read using an Envision plate reader using the following settings:

-   -   Excitation filter—FITC FP 480-Ex Slot 3     -   Emission filter—FITC FP P-pol 535-Em Slot4     -   2nd Emission filter—FITC FP S-pol 535-Em Slot3     -   Mirror module—FITC FP Dual Enh-Slot 1

The inhibition rate is calculated using the percentage of permuted Mahalanobis distances greater than the control samples (mP value) following the equation below:

mP_(c) : themPvalueofcompounds mP_(L) : themPvalueofLowcontrols mP_(H) : themPvalueofHighcontrols ${{Inhibition}(\%)} = {\left( {1 - \frac{{mP}_{C} - {mP}_{L}}{{mP}_{H} - {mP}_{L}}} \right) \times 100\%}$

XLFit (equation 201) is used to calculate a reported IC50 for each compound.

The data from examples A and B are provided in Table 2.

Example C: In Vitro Human Hepatic Clearance in Cellular Relay Format

Working stocks of individual test articles were prepared at concentrations of 100 μM by diluting 10 mM stocks prepared in DMSO 100-fold (v:v) into ACN/H₂O (50/50, v:v). Human cryopreserved hepatocytes were thawed in a 37° C. water bath in <2 min., suspended in thawing media, and then centrifuged at 100×g for 10 min. Thawing media was aspirated, and pelleted hepatocytes were resuspended into incubation media at 1.5 E+06 cells/mL. Cell viability was determined using an Acridine Orange/Propidium Iodine stain, and hepatocytes were further diluted with incubation media to 0.5 E+06 viable cells/mL. Hepatocyte aliquots of 495 μL were added to wells of a 24-well plate, and test article incubations were initiated by the addition of 5 μL of 100 μM working stocks. Plates were incubated at 37° C. in a 500 CO₂ atmosphere at 95% relative humidity on an orbital shaker at 300 rpm. Incubations were performed in duplicate. At time=0 and 4 hrs., aliquots of each incubation were extracted with 6 volumes ACN containing internal standards. After 4 hrs., hepatocytes were removed from the incubations via centrifugation, and supernatants were stored frozen until the following day at which point incubations were reinitiated by diluting thawed supernatants with freshly thawed hepatocytes in incubation media, again to a final concentration of 0.5 E+06 viable cells/mL. These steps were repeated for a total of 5 incubations of 4 hrs. each covering 20 total hours of incubation. Incubational losses due to cellular uptake, nonspecific binding, and dilution at each relay step were corrected for. Supernatants of all incubation aliquots were diluted into ultrapure water prior to analysis via LC/MS/MS. In vitro intrinsic clearances (CL_(int)) in μL/min/1 E+06 cells were determined for each incubation from calculated in vitro half-lives determined using a standard log-linear regression approach. In vitro CL_(int) values were scaled up using the following physiological scaling factors: 99 E+06 cells/g human liver and 25.7 g human liver/kg body weight. Scaled intrinsic clearance values were finally introduced to the well-stirred liver model for the purpose of calculating predicted human hepatic clearance (CL_(hep,pred)) in mL/min/kg assuming a human liver blood flow of 20.7 mL/min/kg and making no corrections for test article binding to red blood cells, plasma proteins, or components of the incubation system. S-Warfarin, Diisopyramide and Diazepam were used as assay controls.

In general, all assays were carried out by following the BPS PARP and TNKS assay kit protocols with a few modifications.

The enzymatic reactions were conducted in duplicate at room temperature in 96 well plates coated with histone substrate. The incubation times were one hour for PARPs 3, 8, 10, 15 and TNKSs, and two hours for PARPs 6, 7, 11 and 14, respectively.

The 50 μl reaction mixtures in PARP Assay Buffer containing: NAD+, biotinylated NAD+ enzymes, with test compounds or reference compounds, were incubated at room temperature for one or two hours. The wells were washed five times with PBST and was further incubated for 30 min with 50 μl Streptavidin-HRP (prepared with Blocking Buffer 3). The wells were washed again and 100 μl ELISA ECL substrate was added to each well.

Luminescence was measured using a BioTek Synergy™ 2 microplate reader.

Enzyme activity assays were performed in duplicates. The luminescence data were analyzed using the computer software, Graphpad Prism. In the absence of the compound, the luminescence (Lt) in each data set was defined as 100% activity. In the absence of the enzyme, the luminescence (Lb) in each data set was defined as 0% activity. The percent activity in the presence of each compound was calculated according to the following equation:

% activity=[(L−Lb)/(Lt−Lb)]×100;

where L=the luminescence in the presence of the compound, Lb=the luminescence in the absence of the enzyme, and Lt=the luminescence in the absence of the compound.

The percent inhibition was calculated according to the following equation:

% inhibition=100−% activity.

The values of % activity versus a series of compound concentrations were then plotted using non-linear regression analysis of Sigmoidal dose-response curve generated with the equation Y=B+(T−B)/1+10((Log EC50−X)×Hill Slope), where Y=percent activity, B=minimum percent activity, T=maximum percent activity, X=logarithm of compound and Hill Slope=slope factor or Hill coefficient. The IC₅₀ value was determined by the concentration causing a half-maximal percent activity.
